| Abstract: | A novel in situ reaction synthesis process, reaction technique in melt, was developed. An in situ particle reinforced Al 4.5 Cu/TiB2 composite was fabricated with low cost TiO2, H3BO3, Na3AlF6 powders and Al Cu alloy. TiB2 particle is very small, about 0.93 μm in size, and it has spheric shape in the solidification microstructure of the composite. The distribution of TiB2 particle in the matrix is uniform. The interface between TiB2 particle and the matrix is combining well. The tensile strength, yield strength and elongation of the composite are 416.7 MPa, 316.9 MPa and 3.3%, respectively, when TiB2 particle contenTin the matrix is 10 vol%. |
